bathroom sink..install oval into round???

[a12548]

i removed our old 19 inch round, which has 18inch opening. We noticed theres no fancy styles for 19 rounds, all the ovals have the shell design that we like, however the oval we measured doesnt cover the front to back depth of old cutout. Are there any standard ovals that will cover that depth, and id just cut a wider width? thanks

Kohler has a Spiria which is 18 7/8" deep. Whether its curve would cover the entire cutout, however, would only be obvious if you had the template to put over your 18" round opening. Kohler also has several fancy rectangular shaped sinks that would work.

the spiria im looking up says 18 3/8, not 18 7/8, is that still enough lip for 18 inch cutout?
